She said: ‘Today’s announcement of the results of the operation marks the culmination of six months of covert work by our dedicated officers.

‘The 37 packages we received are just some of the hundreds of referrals about online child abuse that our Paedophile and Online Investigation team deals with every year.

‘Online child sexual abuse is one of the areas we investigate as part of our work tackling child abuse and child sexual exploitation in general.

‘Online offences can involve actual physical abuse and grooming as well as the making, possession and distribution of indecent images of children.

‘All are criminal offences and a form of child abuse. They are not victimless crimes. Each time an image is shared, it further victimises that child.

‘The fact it’s happening online makes this an international problem but it still can have an impact locally.

‘That’s why it’s important we work together with our national and international law enforcement partners through the National Crime Agency to share information, identify children at risk and bring offenders to justice.

‘Through our Personal Internet and Cyber Safety campaign meanwhile, we’re working to help children stay safe online and prevent abuse happening in the first place.’

If you’re worried about your own sexual thoughts or behaviour towards children, you can get help from the Stop It Now helpline on 0808 1000 900.
